Abstract: A flotation nozzle is described as having an enclosed chamber with unique fluid emitting orifices which are angularly oriented to produce a desired, directional flow of fluid. One such orifice is a dimple-shaped cavity which extends inwardly of the chamber and has a circular opening in the downstream portion of the dimple, relative to the flow of fluid in the chamber. The opening is tilted so that the direction in which the fluid flows from the opening substantially coincides with the resultant velocity vector of the velocity vectors due to static and dynamic fluid pressures at the orifice.
